Vision Based GNC Systems for Planetary Exploration
نویسنده
چکیده
In the frame of planetary exploration, among the Guidance Navigation and Control activities in ESA, Vision Based Navigation is one which has received much attention, because of the flexibility and cost saving aspects associated with camera type sensors. Two applications currently under investigation in this field are: Autonomous Interplanetary Navigation [1] and Navigation for Planetary Approach and Landing [2]. The present paper illustrates the problematic involved, the progresses achieved and the possible future development for these activities in the frame of future missions.

Vision-based Terrain Classification and Classifier Fusion for Planetary Exploration Rovers
Autonomous rover operation plays a key role in planetary exploration missions. Rover systems require more and more autonomous capabilities to improve efficiency and robustness. Rover mobility is one of the critical components that can directly affect mission success. Knowledge of the physical properties of the terrain surrounding a planetary exploration rover can be used to allow a rover system...
متن کاملDemonstration of vision for a planetary exploration rover
The paper describes a demonstration of path planning for a planetary exploration rover, based on stereovision. The demo is limited to the vision subsystem including, on the one hand the stereovision hardware (operating on Mars-like indoor landscape), on the other hand a portable PC whose software has been developed to control the stereovision device, receive the pictures and process them to def...

In recent years, considerable attention has been paid to planetary hoppers for their potential to overcome the limitations on landing precision and mobility facing current planetary surface exploration technologies. This paper describes the development of a unified vision and inertial navigation system for propulsive planetary hoppers and provides demonstration of this technology. A sensor test...
متن کاملAutonomous Navigation System for Planetary Exploration Rover based on Artificial Potential Fields
In this paper a navigation system for an autonomous planetary exploration rover, based on artificial potential fields, is presented. The rover moves to a predefined final position avoiding the obstacles detected by an artificial vision system developed for that purpose. Every obstacle is associated with a repulsive field, while the target point is associated with an attractive field. All these ...
متن کاملVision-Aided Inertial Navigation for Precise Planetary Landing: Analysis and Experiments
In this paper, we present the analysis and experimental validation of a vision-aided inertial navigation algorithm for planetary landing applications. The system employs tight integration of inertial and visual feature measurements to compute accurate estimates of the lander’s terrain-relative position, attitude, and velocity in real time. Two types of features are considered: mapped landmarks,...
